Specification of Letters latent. Application filed March 28, 1910. Serial No. 551,937

Patented June 7, 1910.

This invention relates to pipe couplings,

and the objects of my inventlon are, first, to

" solder or other material provide positive and reliable means for connectin a lead pipe to a wrought iron pipe; secon to obviate the necessity of usi'hg wiped joints inestablishing various fittings; third, to obviate the necessity of using ter-tight connection; fourth, to. provide a coupling with the confronting ends of two soft metal pipes, and fifth, to accomplish such other objects as may the above results by a con ling that can be easily and quickly insta led. These and hereinafter appear are attained by the novel construction, combination and arrangement of parts .to be hereinafter described and then claimed, and reference will now be had to the drawing forming a. part of'this specification, wherein there is illustrated a preferred embodiment of the invention, but 11; is to be understood that the structural elementsthereof can be varied or changed Without departing from the scope of the appended claim.

In the drawings: Figurel is a longitudinal sectional view of the coupling designed for connecting a Wrought iron pipe to a ead pipe. Fig. 2 is a cross sectional View of the same taken on the line :n-m of Fig. 1. Fig. 3 is a cross sectional view taken on the line w'w of Fig; 1. Fig. 4 is a longitudinal sectional view of a coupling. deslgnedjfor connecting the. confronting. ends of two lead pipes, and Fig. 5-is an end view of-the coupling shown in Fig. 1.

In the accompanying drawin the reference numeral 1 denotes a coupling member comprising a body having a longitudinal bore 2 extendindg from one end thereof'to the opposite en This memberintermediate the ends thereof is provided with an'anfnular flange 3 and formed integral with the outer edge of said flange is a sleeve 4 having the inner walls thereof screw threaded, as at 5. The sleeve 4 incloses'the inner end 6 of the coupling member and the periphery for obtaining a wa- --.-said gland is screw threaded to of the member is provided with circumferentiallyarranged ratchet teeth 7., The outer end of the member is exteriorly scre w threaded, as at 8, whereby a WIOU 'ht iron pipe (not shown) can be connected to the coupling member. The flange 3 has I the outer edges thereof provided with fiat surfaces!) to form a hexagon configuration that end of the member l,v and to prevent saidpipe from rotating upon the inner end of the coupling member, the inner. wall of the flange 3 is provided with radially disposed teeth 12 adapted to engage in the end of the lead pipe. To look the lead pi e withln the sleeve 4 a land 13 is employe the bore of the gland eing tapered, as at 14, to conform to'the flared end of thelead pipe, and engage the threads 5with the outer end thereof :hexagen-shaped similar to the flange 3 whereby a wrench can be placed upon the gland to screw the same into the sleeve 4, thereby locking the flared end of the lead ipe in en gagement with the inner end 6 o the coupling member.

In Fig. 4 of the drawings, I have illustrated a modification of .my invention.

wherein the coupling member is constructed to receive the ends of two lead lpes, the coupling member having the annu ar flange "3 thereof provided with a sleeve 15 that incloses both ends of the couplingmember and both ends are identicalin construction similar to the innere'nd '6 previously described. Two-glands areused and the confronting ends of the lead pipes are connected just as firmly as though solder or other material,

were used.

What I claim, is: In a a lead pipe having a flared and enlarged end, of a cou ling member adapted to connect a wrougl ft iron pipe tosaid lead pipe, said member bore "formed .therein extending from one end of said body to the opposite end thereof, an annular {flange carried by said body intermed-iate the ends thereof, a sleeve formed pipe coupling, the combination'with comprising a body having a a and lnclosinfi the inner en integral with the outer ed es of said flange of said member the inner walls thereof said sleeve avin screw threaded, t e inclosed inner end of said member having circiimferentially arranged ratchet teeth adapted to engage in the end of said lead ipe,'radially dlsposed teeth carried by said an e at the inner end of said sleeve and adapte to engagethe end of said lead pipe and prevent a rotation of said pi e upon said ratchet teeth, a gland adapte to be screwed into said-member,

said gland having the borethereof taperedto engage the flared end of said lead ipe, and sai member having the outer end t ere- 15 of threaded and adapted to receive a wrought iron pipe, substantially as a described. i

In testimony whereof I aflix my signature in the presence of two witnesses. LAWRENCE MILLER.
